Subject: [PATCH] pinctrl: ingenic: add missing call to of_node_put()

In one of the error paths of the for_each_child_of_node() loop in
ingenic_gpio_probe, add missing call to of_node_put().

Fix the following coccicheck warning:
./drivers/pinctrl/pinctrl-ingenic.c:2485:1-23: WARNING: Function
"for_each_child_of_node" should have of_node_put() before return around
line 2489.
